The interrupting capacity hits 242 kA at 240 VAC and stays at 187 kA all the way through 440 VAC, then drops to 121 kA at 500 VAC and 4.5 kA at 690 VAC.
Selectivity and coordination — the 240 A minimum matters
The adjustable long-time pickup range runs from 240 A minimum to 1 920 A maximum. That 240 A floor means this breaker won't coordinate below that threshold — if your downstream load draws less than 240 A fault current, the breaker may not see it as a fault. That's typical for a 160 A frame; the pickup range is set relative to the 160 A rating. The 32 A initial value is the starting point for the short-time or instantaneous adjustment, not the continuous rating.
Panel fit — dimensions and environment
Width 105 mm, height 181 mm, depth 86 mm. Communication function is present, so expect a plug-in module or internal bus for remote monitoring; the exact protocol isn't listed here, but the SENTRON 3VA2 series typically supports PROFIBUS or PROFINET via a communication module.
